Abstract

A method and apparatus for splicing programs in the MPEG domain, wherein program data is carried in MPEG transport streams (TS) of data packets. The data packets carry application data, e.g. video and audio data, and a header provided with control data. According to the invention control data objects are established for each data packet for storing time references and data packet status information. The control data objects are queued in different queues dependent on the data packet status or on the status of a group of data packets. Control data objects associated to data packets to be output in an output stream of data packets are selected from the queues, whereupon selected control objects are assembled to a program of associated data packets of different kinds of data. Finally, data packets associated to said selected and assembled control data objects are assembled to an output stream of data packets.
